Dyson was a heretic, Christ is a heretic, Luther was a heretic, Churchill was a heretic ... we NEED heretics! Heretics are always dangerous to the accepted wisdom, and they are often dangerous period -- like people have died because of each of those mentioned. Reality is also dangerous -- the death rate is 100%, and freedom is NOT everyone being treated the same! We are each God's unique creation FOR HIS PURPOSE ... not ours.
A heretic questions the prevailing dogma ... Dyson questions AGW, Christ preaches Grace fulfilling the Law, Luther preached Grace in place of Roman Catholic law, Churchill questioned the belief that suing for peace with Hitler was the only option.
The article is worth the read -- especially in this time of plague in which I am writing, heresy even less popular than it always is. Typically, a time when we need it most!
I will not attempt to summarize the lessons that my readers should learn from these heresies. The main lesson that I would like them to take home is that the long-range future is not predetermined. The future is in their hands. The rules of the world-historical game change from decade to decade in unpredictable ways. All our fashionable worries and all our prevailing dogmas will probably be obsolete in fifty years. My heresies will probably also be obsolete. It is up to them to find new heresies to guide our way to a more hopeful future.
